Title: Disk drive based upon portable medium
Inventor: TERAOKA TADAHIRO
IPC: G06F12/16
Filed: 1997-03-14
Abstract: PROBLEM TO BE SOLVED: To hold the maintainability of a medium in the drive at constant level by inspecting the state of a medium in a storage box in parallel to actual operation by using a drive in a standby state. SOLUTION: To determine a drive unit to be used for medium inspection, a drive unit showing a standby state is found by referring to the drive unit status field of a drive unit management table (S101). Once the drive unit is secured, the drive unit status field is changed into a code showing a medium inspection state and a medium to be inspected is selected (S102). The medium which is selected here is conveyed to the secured drive unit by using a medium conveyance unit. Then the medium is inspected (S103) after the drive unit gets ready for access. The medium inspection is carried out for all the tracks and an error is detected by detecting the no-response time of the drive unit and reporting the error in combination (S104).

Title: Image forming device
Inventor: HAMADA JUNICHI
IPC: G03G21/10
Filed: 1990-03-12
Abstract: PURPOSE:To prevent bounding by forming a thin line toner image almost the same as a cleaning blade width outside of an image area every time a copy is made or intermittently and uniformly supplying toner to the almost full width of the cleaning blade. CONSTITUTION:The CPU of a control part is programmed so that a latent image in the shape of the thin line almost the same as the cleaning blade width is formed outside of a copy image area to be orthogonal to the rotary direction of a photosensitive drum 10 by a laser beam L everytime a copy is made, and that the latent image is developed to form the thin line toner image 20. The thin line toner image 20 can be any of C, M and Y, by which the toner T is suitably supplied to a cleaning edge. By thus forming the thin line toner image 20 outside of the image area, the toner is supplied to the leading edge part of the cleaning blade 19A, and the bounding is prevented from occuring.

CONSTITUTION:A surfacial film 9 formed on the specular surface on an InP single crystal wafer 7, in which treatment damaging layer on wafer 7 surface is ground away by using an abrasive and chemical way, is etched away by a sulfic acid, and a newly formed surfacial layer 8 after etched away is 1nm or less in thickness.

Title: High-frequency power source for plasma generation
Inventor: KATO TSUTOMU
IPC: C23C16/50
Filed: 1994-03-30
Abstract: PURPOSE:To reduce current without suspending a power source even when an over current with rise more rapid than a response speed flows. CONSTITUTION:In the case when an overcurrent with rise more rapid than a response speed of an overcurrent protection system in a limiter system flows from a power source, only a variation of this current from a steady value passes through a condenser 22. When a voltage corresponding, to a current of this variation exceeds a zener voltage Vz of a zener diode 21, a second transistor 20 becames on. Then, a potential at a point 'Q' on the output side of a second operation amplifier 10 becomes a value corresponding to a division ratio of a potential R1 of an outout portion of the first operation amplifier 10 between an emitter resistance R2 of a second transistor 20 and a resistance R1 of an output portion of the first amplifier 10, and a high-frequency output decreases down to a level due to a potential of the point 'Q'. Due to the decrease in the highfrequency output, the current from a power source 11 decreases. When the current value of the variation becomes smaller than Dz due to this decrease of current, a feedback from the first operation amplifier 10 is applied so that the high-frequency power returns to the original state.

Title: Radiation characteristic measuring apparatus for antenna
Inventor: ONO MAKOTO
IPC: G01R29/10
Filed: 1983-04-07
Abstract: PURPOSE:To enable the measurement of a sample antenna using a fine power by integrating a received radio wave after a digital conversion to improve the S/N ratio while varying the integration time. CONSTITUTION:After the output of a receiver 4 is detected with a phase detector 6, it is converted into a digital signal with an A/D converter 7. This digital voltage is integrated with an integrator 8. When M digital voltage values are inputted into the integrator 8 from a converter 7 within a certain integration time, the S/N ratio of the voltage after it outputted from the integrator 8 is integrated is compared with that thereof before the integration and improved by M times. Therefore, the longer integration time can improve the S/N ratio of the voltage more after the integration. The adjustment of the integration time can be done by controlling the speed of a rotary base 5 where a sample antenna 3 is mounted. This can reduce the transmission power as sufficient improvement is possible despite the limited S/N ratio of the output signal of the receiver 4.
